VENTILATING-DEFLATOR.

I Specification of Letters Patent.

Patented July 23, 1918.

Application filed October 23, 1916. Serial No. 127,139.

To all whom it may concern:

Be it known that I, ERNEST D. PORTER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Ventilating- Deflators, ofwhich the following is a speci-.

fication.

My invention relates to a rectal ventilating deflator. I

It is an object of this invention to provide a device simple in construction and inexpensive of manufacture to be used in the treatment of cases of fiatulency and constipation. The device comprises a hollow tube, closed at both ends, and provided with ventilatin apertures at the ends, which is inserted in the rectum, affording a constantly open passage to gases generated in the intestinal canal. The outer enlarged end is provided with a removable cap whereby the interior of the device may be easily cleaned and kept in a sanitary condition. a

My invention'consists in the construction parts hereinafter described and claimed.

In the accompanying drawings forming a part of this specification, I have shown a practical embodiment of my invention, and in which:

Figure 1 is an elevation of the device.

Fig. 2 is a vertical cross section taken on line 2-2 of Fig. 1.

Fig. 3 is a. horizontal cross section taken on line 33, Fig. 1. i v I Fig. 4 is an elevation of a modification of the invention.

Fig. 5 is an elevation of another modification of the'invention, and Fig. 6 is a section taken on line 66, Fig. 5.

The deflator comprises. a tubular body 10 cylindrical in shapeyprovided at one end with a slightly enlarged head, 11, spherical in shape. At the other 'end an enlarged gas discharge chamber 12 is provided which is formed by an upper section 13 having an internal sorewthread in which a lower section 14 is screw threaded. The two sections form a smooth joint. The enlarged gas chamber serves also as a retaining shoulder to maintain the device in proper position. At the under face of the lower section 14, and coaxial with the tube 10, is

a square boss or In 15, whereby thelower section may be easi y unscrewed.

A plurality of apertures 16 are provided in the head 11. Similar apertures 17 are providedin the upper section 13.of the gas discharge chamber 12.

In the use of the'device, a lubricant such as oil, is preferably applied to the head and tube prior to its insertion in therectum. The device is preferably used durin the night, though the same may be 'use and retained in the rectum during the day, as very little inconveneince in retaining the device is experienced. I have foun 3%,} inches, total length, with a diameter of the tube of ,3 inch. Any suitable material, such as hard rubber, metal or the like may be used in the construction. The gases gen-- of the device for cleaning purposes may be" had.

In the modification shown in Fig. 4, the tubular section 10' is' given a slight helical twist. This shape of the tube has the advantage of being more firmly held in position by the muscles of the rectum.

the following dimensions to give good results:

By making the device of metal, ele'ctric treatment'may be combined with the normal function of the device by connecting the same to a source of electric energy.

In Figs. 5 and 6 Ihave shown still another modification in which a helical groove 18 havin rounded edges is provided on' the perip cry of the tubular member 10.

The groove 18 allows the muscles of the rectum to grip the device and to holdthe same in place. I

I claim: v

1. In a device of the character described, the combination of'a rigid cylindrical tube havin a perforated head at one end, and an enlarged perforated gas chamber at the other end, said chamber constituting a tube retaining shoulder, and comprising an upper section fast to said tube, and a lower section screw threaded on said upper section, and a lug depending from said lower section whereby said lower section may be,

operated.

2. In a device of the character described, the comblnatlon of a rigid cylindrical tube havlnga perforated head at one end, and

an enlarged perforated gas chamber at the other end, said chamber constituting a tube retaining shoulder, and comprising an upper section fast to said tube, and a lower section screw threaded on said upper section. 1

3. In a device of the character described, the combination of a rigid cylindrical tube having a perforated head at. one end, said tube having means on the periphery thereot', whereby the same may be held in operative position, and an enlarged perforated gas chamber at the other end, said chamber constituting a tube retaining shoulder, and

at I I 1,273,665

comprising an upper section fast to said tube, and a lower section screw threaded on .on the periphery thereof, and an enlarged.

perforated gas chamber at. the otherend, said chamber constituting a tube retaining shoulder, and comprising an upper section fast. to said tube, and a lower section screw threaded on said upper section.

In testimony whereof l have signed my name to this specification.

. ERNEST D. PORTER.
